Try rolling a ball up or down these ramps into a target or to a friend. Improved ability to stabilize vision/gaze. Signals are sent from the semicircular canals using only three neurons, called the three neuron arc. They are frequently prescribed to patients with vestibular hypofunction with the aim of improving the gain of the vestibular ocular reflex, improving visual acuity during head movement, and reducing the symptoms of dizziness and vertigo.

Despite research efforts, chronic ankle instability (CAI) continues to affect approximately 30% of individuals who sustain ankle sprains. The vestibulo-ocular reflex (VOR) is a gaze stabilizing reflex: the sensory signals encoding head movements are transformed into motor commands that generate compensatory eye movements in the opposite direction of the head movement, thus ensuring stable vision.

VOR is reflex where Activation of vestibular system causes eye movements This . <>>> The vestibulo-ocular reflex needs to be fast: for clear vision, head movement must be compensated almost immediately; otherwise, vision corresponds to a photograph taken with a shaky hand. These data have implications for vestibular rehabilitation, suggesting that quality and duration of VOR adaptation exercises are more important than rapid repetition of exercises. Head trauma can cause impairments in Oculomotor and VOR function, resulting in an array of symptoms including: slower reading, decreased comprehension, skipping words, missing objects, blurriness, eye fatigue, headaches, foggy headedness, movement-related dizziness and nausea. The exercises were performed for approximately 5 minutes daily or 1 to 2 minutes, 3 to 4 times a day, in sitting position.
